AT&T says HSUPA capabilities coming via updates
AT&T's purportedly intentional blockage of HSUPA upload speeds for its Motorola Atrix 4G and HTC Inspire 4G, among others, will soon be put to an end, BGR has found. An AT&T spokesperson hinted update will come to current devices to bring HSUPA speeds for uploading. The iPhone 4 and some modems are so far the only devices that can use the faster 3G.
"We have a number of HSUPA devices today and we will have more HSUPA-enabled devices in the future -- new devices and updates to existing models," the spokesperson said.
AT&T's decision to limit many to HSDPA, which has the same 7.2Mbps downloads but limited uploads, is believed to have been for testing and certification reasons rather than attempts to favor particular devices. It's still unknown why the iPhone 4 was approved so early, but its status as the most popular AT&T smartphone may have helped.
